3. Sound Quality Testing
3.1 Bass Response
This is primarily due to the dynamic driver found in the FH1S that delivers deep and earthshaking bass.
Test tracks: Tracks such as “Royals” by Lorde or “Billie Jean” by Michael Jackson have some of the dopest bass lines in the world.
Performance: The FH1S appears to have an impressive bass response while completely ignoring the midrange and treble. It controls the bass low and extends well, giving a satisfying low-end presence. A little certain bloom might affect some of the clarity with songs that do extreme bass.
3.2 Midrange Clarity
One can hear clearly the mids as clear and detailed.
Test Tracks: Songs that might be included in this category would mostly be vocal-centric. Examples of such include “Someone Like You” by Adele and “Blackbird” by the Beatles.
Performance: As a result, FH1S is excellent in terms of clear and detailed midranges. The vocals are forward and well-resolved, representing instruments well. Midrange performance is very well balanced and suitable for most music genres.
3.3 Treble Extension
The treble frequencies are adjusted so that they remain present but are devoid of harshness.
Test Tracks: Tracks focusing on higher frequencies such as “Hotel California” by Eagles and “Clair de Lune” by Debussy.
Performance: The treble extended yet smooth, with good detail but not sibilant. FH1S goes all the way in being able to portray high-frequency information, but it probably is not as sparkly as some higher-end models. When taken as a whole, treble balances itself, giving to an overall sound signature.
3.4 Soundstage and Imaging
Soundstage and Imaging are what bring realism in listening experience.
Test tracks: Tracks with space effects such as “Bohemian Rhapsody” by Queen and “Space Oddity” by David Bowie.
